In this work, carbon nitride ( C 3 N 4) nanoparticles (NPs) were synthesized by pulse laser ablation of graphite in ammonium solution, and deposited on silicon substrates by spray. Fourier transform infrared spectroscopy (FTIR), UV-visible spectrophotometer and transmission electron microscopy (TEM) were used to study bonding, absorption, size and morphology of the produce NPs. The FTIR absorption peaks at 2121.6, 1631.7 and 1384 cm-1 stretching vibration bond, it is inferred for the C ≡ N , C = N and C – N , respectively. Bonds suggests the formation, C 3 N 4 NPs. UV absorption peaks coincide with the electronic transitions corresponding to the formation, C 3 N 4 NPs with 3.98 eV optical bandgap. The TEM show the aggregation of the C 3 N 4 NPs with size ranges from 4 to 83 nm, and also the leaf-like structure are shown in the structure of C 3 N 4 suspension. High performance rectifying C 3 N 4/ Si heterojunction with a rectifying ratio exceeding 345 at V = 5 V was obtained, with high photoresponsivity of 2.33 A/W at 600 nm.The results show that C 3 N 4 NPs on silicon substrates will act as very good candidates for making high efficiency photodiodes.

Sers Sensing

This paper reports a simple and versatile method with innovative application of photoresist film for fabricating ordered nanodot arrays with tunable structural parameters as large-area surface enhanced Raman scattering (SERS) substrate with high performance. The substrate is fabricated by evaporating Au on the regularly patterned aluminum template of pits arrays formed from the anodization of Al. A key point in our method is coating a photoresist layer on the fragile Au film to support the film before separating it from the Al template, which insures the integrity of the film on large area. Taking Rhodamine 6G as probing molecules, SERS spectra are investigated. The convenience of preparation as well as the high performance for the SERS signals makes the prepared substrates a promising candidate for SERS sensing or detecting.

AbstractThis work examines the adhesion of coatings derived from divinylsiloxane bisbenzocyclobutene, mixed stereo and positional isomers of 1,3-bis(2-bicyclo[4.2.0]octa-1,3,5-trien-3-ylethenyl)-1,1,3,3-tetramethyl disiloxane (CAS 117732–87–3), on oxidized silicon substrates treated with silane coupling agents.This material, commercially available as Cyclotene™ 3022, can be used in the construction of high performance electronic circuits, such as multichip modules. Silane coupling agents examined in this study were 3-aminopropyltriethoxysilane (CAS 01760-24-3)(APTES)(, vinyltriethoxysilane (CAS 00078–08–0)(VTES), and 3-methacryloxypropyl trimethoxysilane (CAS 02530–85–0) (MOP-TMS).Measurement of the interfacial adhesion was performed using microindentation. Bond strengths obtained by this method exceed 200 MPa for the most effective coupling agents. However, these high bond strengths were not found to correlate with acceptable adhesive performance in all cases. In addition to the choice and preparation of the coupling agent, process related chemical exposure has been found to be a key element in the observed adhesive performance. The effect of the cure schedule for the thermoset coating has also been found to be a controlling factor. A short cycle test vehicle was developed consisting of a single 20 gIm polymer layer etched with anisotropic sidewalls. This test vehicle was used to evaluate the efficacy of the coupling agents during process exposures and subsequent thermal shock testing. A solution of MOP-TMS pre-hydrolyzed in methanol was found to produce the most reliable interface with high bond strength.
